Uncovering temporal patterns of wildlife activity, habitat use and habitat preference from camera‐trap data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract An understanding of habitat use and levels of active behaviour is foundational to wildlife behaviour, ecology, conservation and management. These variables are commonly measured by tracking individuals in space and time using biologging. In principle, camera‐trap data also contain information about both activity level and habitat use; however,

Mikrostruktur dan Karakteristik Permukaan Kayu Pinus Scots (Pinus sylvestris L.) Termodifikasi Gliserol dan Asam Sitrat

open access: yesJurnal Ilmu Pertanian Indonesia
Scots pine (Pinus sylvestris L.) wood is one of the most popular timber export products. However, its low durability can reduce the potential and utilization of the wood. Chemical modification is one of the solutions to overcome this drawback.

Programmed cell death and genetic stability in conifer embryogenesis [PDF]

open access: yes, 2007
Somatic embryogenesis, the generation of embryos from somatic cells, is a valuable tool for studying embryology. In addition, somatic embryos can be used for large-scale vegetative propagation, an application of great interest for forestry.

TreeON: Reconstructing 3D Tree Point Clouds from Orthophotos and Heightmaps

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present TreeON, a novel neural‐based framework for reconstructing detailed 3D tree point clouds from sparse top‐down geodata, using only a single orthophoto and its corresponding Digital Surface Model (DSM). Our method introduces a new training supervision strategy that combines both geometric supervision and a differentiable shadow and ...

A review of thinning effects on Scots pine stands: From growth and yield to new challenges under global change

open access: yes, 2017
Aim of the study: Thinning experiments in Scots pine ( Pinus sylvestris L.) stands have been carried out for many years in different regions of its distribution. The aim of this paper is to gather knowledge regarding the effects of thinning on Scots pine

Effects of restoration practices on biodiversity in temperate and boreal forests

open access: yesConservation Biology, EarlyView.
Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Living on the edge – physiological tolerance to frost and drought explains range limits of 35 European tree species

open access: yesEcography, EarlyView.
Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

Analysis of differences of growth and phenology of provenances of Scots pine (Pinus sylvestris) in provenance experiment at Žepče

open access: yesBiosystems Diversity, 2017
This paper analyses the growth and phenology of fourteen European provenances of Scots pine at the international experimental plot at Zepce. The experiment with the provenances was developed during the spring of 2012 with two (2+0) year old plants.

X-ray based tree ring analyses [PDF]

open access: yes, 2004
In this thesis, two x-ray based dendro-analyses (batch-wise microdensitometry and energy dispersive x-ray fluorescence (EDXRF)) and the conditions under which these methods could be used on the two typical boreal conifers Norway spruce (Picea abies (L ...

Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

open access: yesEcological Entomology, EarlyView.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .
